True to its name, the wyvern resembles that of the enormous winged wyvern, with large red bat-like wings, a pair of legs and a tail. The red membrane of the wing is translucent. Roshan has rough black scales, with white bone-like spines along her body, including an external skull, rib cage and rows of dorsal spikes. She oftenly known as "Queen of Monsters" since the wyvern is shown to have the unique ability to spawn many smaller grimm clones via a dark ooze that drips off her enormous body.
